These Meters are excellent diagnostic instruments for detecting temperature and humidity.
TSI’s TH-CALC™ Meters are excellent diagnostic instruments for detecting temperature and humidity. Each hand held instrument measures multiple parameters. The Model 8720 measures temperature, humidity and calculates dewpoint. The Model 8722 adds data logging, and performs wet bulb temperature, absolute humidity and % outside air calculations. These instruments are ideal for conducting thermal comfort studies and Indoor Air Quality (IAQ) evaluations.
Features
Direct calculation of dewpoint temperature
Sampling function records multiple point measurements
Optional portable printer provides hard copy documentation of your measurements
View two parameters simultaneously from the large digital display
Additional Features and Benefits of the Model 8722
Direct calculation of wet bulb temperature and absolute humidity - no psychrometric chart needed
Automatically calculates % outside air after taking necessary temperature readings
Optional detachable secondary temperature sensor
Data Logging Capabilities of the Model 8722
Data logging ability allows user to log 14,000 samples with a time and date stamp
Simultaneously records all parameters available
Continuous data logging for cyclical monitoring and trend analysis
Discrete data logging for taking spot measurements
Data can be reviewed on-screen, printed or downloaded to a computer for easy report generation
TSI LOGDAT™ downloading software permits easy transfer of data to a computer
LOGDAT™ Companion Excel® Macro automatically graphs your data
Statistics function displays average, maximum and minimum values, and the number of recorded samples
